16単位まで再履修が可能で、一番最近履修した等級と点数だけがGPAに反映される（つまり上書きされる。スタンフォード方式）。

UCLA では悪い等級を取った学生は再履修しようね。単位を増やしたければ再履修しようね、と積極的に勧めているように見える。

To improve the grade-point average (GPA), students may repeat only those courses in which they receive a grade of C− or lower; NP or U grades may be repeated to gain unit credit. Courses in which a letter grade is received may not be repeated on a P/NP or S/U basis. Courses originally taken on a P/NP or S/U basis may be repeated on the same basis or for a letter grade.

For undergraduates who repeat a total of 16 or fewer units, only the most recently earned letter grades and grade points are computed in the GPA.
